see Rossellini herself. Rachel encourages Ross to pursue her, knowing he'll get shot down; Rossellini is somewhat charmed and intrigued by Ross's "list," but leaves after seeing that she is not on the final version (quipping that she has a list of five coffee house guys, but she has just bumped Ross off her list). Tomas and Tim Tomas (Robin Williams) and Tim (Billy Crystal): two strangers at the coffee shop. Appearing at the beginning of "The One with the Ultimate Fighting Champion", they perform a superfluous skit while sitting on the group's sofa at Central Perk. Tomas confides to Tim that he thinks his wife is cheating on him with her gynaecologist, causing the friends stop trying to have their own conversation and eavesdrop. Eventually Tim reveals how he's sleeping with Tomas' wife; bursting into tears, Tomas starts shouting at and insulting Tim, and leaves the shop in a loud fury, followed by Tim, who gives the six shocked, bewildered friends one last embarrassed, apologetic look before he leaves. Robin Williams and Billy Crystal were filming nearby and adlibbed all their lines, and were uncredited. Only in season 4 Kathy Kathy (Paget Brewster): Joey's girlfriend, introduced in "The One with Joey's New Girlfriend" (airdate October 30, 1997; season 4, No. 5). A mutual attraction soon develops between Kathy and Chandler, which manifests in a kiss; Kathy then breaks up with Joey, without telling him why. After Chandler reveals the truth, Joey is outraged and decides to move out, but has a change of heart after hearing Kathy's feelings for Chandler, and she and Chandler get together. Although Chandler is initially uncomfortable about the possibility of their relationship becoming sexual as he would be directly compared to Joey, Monica and Rachel are able to give Chandler some pointers. Sometime later, Chandler goes to see Kathy in a play and becomes jealous of her steamy onstage sex scenes with her co-star, Nick. Chandler starts to suspect that she is cheating on him; when he confronts her about it, she leaves, offended, and Chandler assumes the worst. Realizing that he has come to the wrong conclusion, Chandler arrives at Kathy's apartment the next morning to apologize to her, only to find Nick's pants, and they break up. When Paget Brewster arrived for her audition, she believed she was the "runty alternate" and did not have a chance of getting the part. Matthew
